shear and compressional wave velocities along with other petrophysical logs, are considered as upmost important data for hydrocarbon reservoirs characterization. shear wave velocity (vs) in well logging is commonly measured by some sort of dipole logging tools, which are able to acquire shear waves as well as compressional waves such as sonic scanner, dsi (dipole shear sonic imager) by schlumbe...

Drilling industry and its technical services are among the complex and advanced technology-based industries in the cycle of oil exploration and production. In this regard, the logging services role as one of the pillars of technical services is very important due to technological complexity and the importance of the results in the evaluation of oil and gas reservoirs. The complexity had caused ...

In the rollback recovery of large-scale long-running applications in a distributed environment, pessimistic message logging protocols enable failed processes to recover independently, though at the expense of logging every message synchronously during fault-free execution. In contrast, coordinated checkpointing protocols avoid message logging, but they are poor in scalability with a sharply inc...

The logging industry remains one of the most hazardous in the nation. Despite more stringent safety regulations and improvements in equipment safety features, the rate of logging fatalities has decreased at a much lower rate than the decrease in the rate of illnesses and injuries in the same occupation. The objective of this research was to identify and assess the hazards associated with loggin...

This paper assesses the technology involved in commercial forest harvesting and delivery operations. It investigates existing forest-based production capacity and its potential to supply the startup of large scale forest-based industries. A survey of harvesting and transportation workforce and technology was mailed to 1,130 logging firms operating in Michigan and four Wisconsin counties that ad...

Production variability is a significant determinant of logging investment outcome. This variability may result from either process variation or zero production weeks. Using assumptions for a “typical” Southern logging system, the Auburn Harvest Analyzer and a simulation model, the impacts of production variation on logging cost, investment return and risk were estimated. The expected value of l...

Up till now, there is no production logging data interpretation module in CIFLog, which is the 3rd generation well-logging software platform in China. So the situation has a strong impact on its promotion and utilization. In this paper, firstly, the authors introduce the characteristics of the existing and mature logging interpretation software, and design the data interpretation module functio...
